    Actually now that I think of it my ringing seems to have gotten louder after I started using them. I wonder if that noise cancelling is doing something to the brain or hears.

      I experienced discomfort, like mild pain too. I thought maybe it was because the addition of extra sound to cancel out sound increased the total volume in a way that was inaudible, but I don’t really know the physics behind how the cancellation works. This article says it is an effect caused by pressure similar to how your ears pop at different altitudes.
